About
Data Scientist with 6 years of experience building machine learning models and analytics pipelines for e-commerce and fintech products. Trains and deploys models in Python with Scikit-learn and PyTorch, from feature engineering through A/B testing in production, and explains the results to people who will never read the notebook. Recent work includes a recommendation engine and a fraud model that lifted recall from 71% to 89%.
Experience
